Certain types of metal such as aluminum and stainless steel (an alloy of metal elements such as chromium or nickel) also oxidize, but the oxidation forms an oxygen proof layer on the surface, after which the process stops automatically. But the corrosion that occurs on other metals like iron and steel, is a process that unfortunately will continue indefinitely, if you don’t stop it.
Rust continues until something is done to stop it, or until all the metal is converted into the well-known green-brown granular and brittle mass. The rust must be removed and new metal, and a new protective layer, have to be applied (and that usually means welding).
The rust is removed, but Ferguson also creates a perfect adhesive layer on which the new protective lacquer can be applied. The corroded metal does not need to be sanded clean, although it is advisable to remove larger and flaking parts of rust first.
Also, the effects on the metal of chemicals such as salt, oil, and gasoline are stopped by Ferguson. No matter how well cars, bicycles and garden materials are protected, as soon as a scratch or dent damages the paint or coating, the corrosion begins.
Because even a small rust spot on the outside can mean the other side of the metal is already severely compromised. Fortunately, there is a good solution for removing the rust and immediately provide the metal with a new protective layer.
With Ferguson you can stop the corrosion process and it also is the perfect primer for virtually any finish. Rust is one of the common problems that most of us face if we have an old model of vehicle.
This is the reason why rust prevention is the best way for you to deal with this kind of situation. If you were not able to treat this, then rust will give you a total failure on the component that is affected.
Tannin acids are usually combined with Iron Oxide that will form a stable compound which is called Mandate. Rust converters usually come with a polymer that serves as a protective layer.
This is also a compound that is made to rise the chemical process with the tannin acid. This will convert the rust on the material into a protective chemical barrier.

Once that you have applied the rust converter to the affected area, leave it and let it dry. In case you are asking if you can use a powder coat over a rust converter, then the answer to this is still not tested.
It is not actually recommended applying a powder coating over a rust converter product as well. Before applying a rust converter, make sure that you wear protective glasses together with a glove that is chemical resistant.
Keep in mind that rust converter is dangerous once it is ingested and this will require treating immediately. Though vapors from the rust converter are not harmful still it is recommended that you apply the mixture on an area that has proper ventilation.
You can only apply the rust remover when the surface of the material is above 50 degrees Fahrenheit. Do not spill any used rust converter back into your bottle You can only use oil-based paint as your top coating Never use Latex paint If you are going to dispose of any unused rust converter, you might want to consult it with a local regulatory agency.
Rust stains are difficult to remove because of their bright color and stubborn resistance to typical cleaners like bleach and soap. Rust removers aren’t good for delicate like wool or silk, but for most other surfaces, you’ll find your solution below.
Naval Jelly, a phosphoric acid-based, caustic rust remover, is suited for heavily rusted iron or steel, but should not be used on delicate materials like fabrics, as well as aluminum, chrome, stainless steel, cement, fiberglass, marble, plastics, or painted surfaces (it will remove paint). On the plus side, naval jelly gets rid of rust in about five to 10 minutes and any excess product can be removed and cleaned with water.
While not as corrosive or toxic as acids, these products often use pressurized gases for dispersal, which are flammable and may have respiratory risks. Research from the U.S. General Services Administration also shows its power to remove rust stains from concrete, limestone, and marble.
In home cleaning products, sodium hydrosulfite eliminates the need for scrubbing away stains and can be used in bathrooms, toilets, kitchens, and washing machines. Typically, these products require you to soak rusty items for a minimum of 30 minutes to overnight, time well spent that results in rust -free, stain-free tools and surfaces.
Soaks are best for removing rust from tools, automotive parts, and other metallic surfaces you don’t want to scratch by scouring with abrasive pads or harsh acids. Powered rust removers can also be added to your washing machine and toilet bowl, making them ideal for homes with high iron content in the water supply.
If you live in an area with hard water and high iron content, consider keeping a bottle handy to banish corrosion not only on (and within) plumbing and appliances, but also from clothing and fabrics. Just brush this water-based formula onto any rusty surface (except stainless steel and galvanized metals) and let it dwell 24 hours until fully dry and cured.
It works wonders on rusty tools, outdoor equipment, car parts, stainless steel, plastic, ceramic tile, glass, and fiberglass surfaces and is also a great alternative to ammonia- and bleach-based products on hard water deposits, soap scum, and rusted toilets. I had read about this several times, and finally decided to give it a try on a recent project.
This was a small setup, and could easily be modified into a large one for bigger parts. I could easily see a 10 gallon fish tank and battery charger for cleaning up some vintage tools.
Making my first Intractable was harder than playing home chemist. This is a fantastic way to remove rust and oxidation from steel and iron.
It is not recommended for brass, aluminum, copper or exotic metals and alloys. Your anode is your sacrificial lamb in this process, and gets connected to the positive/red/hot side of your electric supply.
The amazing process of electrolysis will erode the anode away over time. I think in a large set up a piece of flat steel or maybe some rebar would work well.
* the black film can easily be cleaned off with a slight abrasive such as a scotch write pad * make sure you treat the newly cleaned metal asap since it will easily and quickly begin to rust again.
With one natural ingredient, it’s easy to remove rust from heavily corroded antiques, artifacts, and tools. Looking at it, I thought it would be a nice keepsake- and something I could use to create an equestrian project with sentimental value- but it was covered with layers of rust.
I’d been experimenting all winter with using citric acid to clean rust off garden tools that I, in my distract ability, tend to leave out in the elements. As it turns out, the basic combination of citric acid, water, and time completely removes rust from metal.
A lot of the comments have suggested replacing citric acid with vinegar and soaking a little longer, and I wondered it this would work as well, so I recently did some experiments. At the bottom, you’ll find a price breakdown (spoiler: there’s a clear winner) and some important safety information on using alternative household chemicals other than the very safe one described in this tutorial below.
A bucket or plastic container large enough to hold your rusted object(s) Very hot water A surface treatment for raw metal. A tablespoon of Citric Acid is great for boosting dishwasher detergent, descaling coffee makers, getting grime off pots and pans, removing hard water stains, and general cleaning.
You can use it in cooking too- soaking cut apples in a weak citric acid solution to prevent browning, or adding a tablespoon to bone broth at the beginning of the cooking process to help break down bone and transfer nutrients into your broth. With one safe, natural ingredient, it’s easy to remove years of rust from antiques, artifacts, and rusty tools- all with no scrubbing required.
It sounds intense, but Citric Acid in the following concentration is very safe- just a little more punch than average household vinegar. I add about 1/3rd cup of powdered citric acid per gallon of water, but you can use slightly more or less depending on how rusty your object is and how quickly you need results.
In this image, I’m defrosting a found old horse shoe and I’ve tossed in some rusty bolt cutters. When the bubbles rise to the surface and the water turns yellow, you’ll know the solution is working.
Some items will be rust free in hours, while others may take a full day or multiple soaks. The above image is how my rusty objects looked after 2 hours in the solution and a quick wipe with a paper towel.
When finished, the solution is safe to discard down a drain- the chemical reaction that dissolves the rust will have neutralized the acid, making it harmless for most household pipes (if any pieces of rust have broken off and settled at the bottom of the bucket, do NOT put these down a drain, and instead discard in the garbage). The metal may seem “dirty” and transfer dark marks on your hands when touched- this is normal for steel and iron with no protective coating.
After wiping with a paper towel, a 30-second scrub with a steel brush produced the dramatic result shown above (After only 2 hours soaking in the solution! In this photo you can see the yellow-tinge the solution takes on as it is working, as well as the loosened rust sediment that will settle in the bucket.
Since published, this article has traveled far and wide and collected a lot of feedback comments- many advising to “just use vinegar” was a comparable technique. Adding 3 teaspoons of citric acid powder to 1 cup of water lowers the pH a full point.
Comments on this post have casually suggested “heating vinegar and then adding salt” to create a rust -busting cleaning solution- but this is VERY unsafe. Combining heated vinegar with salt creates hydrochloric acid fumes, which are toxic and potentially fatal in large doses.
Given that the citric acid solution is stronger, and thus faster acting, it’s the better choice for rust removing with this method. Lindsayanne is a professional artist, writer, and serial-DIY-er with a knack for solving problems creatively at home, in the studio, out in the garden, and even online.
